One, Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-craft and the unsuccessful Welman submarine, were specifically designed with this in mind. The sinking of the USS West Virginia and capsizing of the USS Oklahoma may have been accelerated by a torpedo hit from a submarine-launched torpedo, the warheads of which were larger than the aerial torpedoes. lines citing the organization name: "Naval Historical Center". Four of the five Pearl Harbor midget submarines have been found and definitely identified for what they are. Pearl Harbor. Pacific War. east coast of Oahu and was captured there the day after the attack. spotted trying to enter the harbor before dawn, was attacked and ", This class was followed by: Type B (甲標的乙型, Kō-hyōteki otsu-gata), Type C (甲標的丙型, Kō-hyōteki hei-gata), and Type D (甲標的丁型, Kō-hyōteki tei-gata), the last one better known as Kōryū (蛟龍).[2][3]. There was also a demolition charge which it has been suggested was large enough to enable the submarine to be used as a suicide weapon, but there is no evidence that it was ever used as one.

Some believe that in the photo, where the torpedoes' paths had supposedly started, were sprays that indicated a midget-submarine rocking up and down due to the force of the torpedo being launched, causing the propellers of the stern to be exposed, kicking up clouds of water spray.

It was visited at approximately 6:30 am local time, by an Okeanos explorer ROV, on 7 December 2016, 75 years after it was sunk. There are four Type A midgets on display in the world: No.8 on display at the Submarine Force Library and Museum, The stern of No.8 showing contra-rotating propellers. A photograph[9] taken from a Japanese plane during the Pearl Harbor attack shows what might have been No.16 inside the harbor firing its torpedoes at Battleship Row.
In late August 2002, the submarine sunk by USS Ward was located by the Hawai'i Undersea Research Laboratory in deep water, some five miles off the entrance to Pearl Harbor. Raised and returned to Japan, it is now on exhibit at Eta Jima. The crew of one of the submarines, Lieutenant Saburo Akieda and Petty Officer Masami Takemoto, beached their submarine (No.20b) at Nosy Antalikely and moved inland towards their pick-up point near Cape Amber. observers to argue that one of the midgets was in place off "Battleship Row" as the Japanese torpedo planes came in, and may have fired its torpedoes at USS Oklahoma (BB-37) or USS West Virginia (BB-48).

This contention is controversial, and is mentioned here strictly as a matter of possible interest. see: Click on the small photograph to prompt The Japanese Navy included five Type A midget submarines in You may need to download version 2.0 now from the Chrome Web Store. the Pearl Harbor attack, see: For additional images of Japanese Type A, B & C midget submarines, [1], The midget submarine attacked by Ward (DD-139) at 6:37 a.m. on 7 December, No.20, was located in 400 meters (1,312 feet) of water five miles outside Pearl Harbor by a University of Hawaii research submersible on 28 August 2002. The crew's remains are still entombed in the submarine. However, as circumstances changed, they were given the task of harbor penetration. •

Most of the other fifty are unaccounted for, although three were captured in Sydney (Australia), and others in Guam, Guadalcanal, and Kiska Island, accounting for some of the other hull numbers. The battered wreck of the one sunk by USS Monaghan was savaged a few days later and subsequentlly buried in a landfill at Pearl Harbor. Some images linked from this page may bear obsolete credit

So, at this point, any contention that this midget is the fifth one from the Pearl Harbor attack must be approached with caution.

THE LAST CAMPAIGNS By the end of 1942, the Imperial Japanese Navy worked to redesign and redeploy the kō-hyōteki. Ramillies was later repaired in Durban and Plymouth.

Some four hours later, having recovered, it entered the harbour, but it was subsequently attacked with depth charges and sunk in Taylor Bay by vessels of the Royal Australian Navy. A war time report from Admiral Nimitz confirmed the recovery of at least one dud torpedo of the type employed by the midget submarines. They were also called "Tubes" (筒, Tou) or "Target" (的, Teki, abbreviation of 'Hyōteki') and other slang names.
